So Stubbonrn.

Little Jonny didn't want to eat anything. His mother was so afraid that she took him to a psychology doctor. The doctor tried many ways, but still didn't get any result. At last, the doctor asked:

Alright, What do you want to eat?

Pest! He answered.

Thought that is was a good treatment method, the doctor required a nurse bring it a cup full of pests.

Here you are! The doctor said to Jonny.

But I want to fried one!

The nurse made fried pests. Then Jonny gave another requirement:

I need just one pest!

So one pest was left on a dish. Jonny continued: 

The doctor must eat a hlf of this pest!

The doctor tried all his pest to swallow a half of the pest and gave the left half to Jonny. Jonny shouted:

I don't eat! You already ate one half the pest! That is the hafl I want to eat...
